Patented Nov. 24, 1914.

To (116 whom it may concern:

Be it known that I, OTTO \VINKLER, a subject of the King of Prussia,residing at Ciipenick, Germany, have invented certain new and usefulImprovements in Self-Levcling Carbureters, of which the following is aspecification.

This invention relates to charge-forming devices for internal combustionengines, and has especial reference to the engines used to driveaeroplanes. When a float-controlled carbureter is employed in an enginepropelled flying machine, difliculties have arisen from the inclinedpositions assumed by the machine, which not only prevent the freemovement of the float but also bring the level of the gasolene too farbelow or above the nozzle opening to permit proper vaporizing. Inconsequence of this, the composition of the mixture is unfavorablyaffected.

My invention is intended to remedy these troubles and to this end itcomprises means for mounting the float chamber and nozzle in such amanner that they will be selfleveling, oscillating freely in alldirections about a point which preferably coincides with the mouth ofthe nozzle.

In the accompanying drawing, Figure 1 1s a sectlonal elevation of afloat carburetor embodying my invention, and Fig. 2 is a sectional planview of the same on the line The intake pipe 1 of the engine isstationary with respect to said engine. and is provided with thecustomary throttle valve 2 for the mixture. The open end of said pipethrough which air is-drawn is a bellshaped funnel 3. The nozzle 4 of thecarbureter is located inside of this funnel, and is connected by thepipe 5 with the float chamber 6. I

The chamber and nozzle are not rigidly connected to the intake pipe, butare cardanically suspended thereon, on axesintersecting at right anglesat the mouth! of the nozzle 4. For example, the chamber 6 and an arm 8extending from the pipe 5 are pivoted on trunnions 9 at diametricallyopposite points on a ring 10 which lies in the lane of the mouth of thenozzle and'in turn is mounted on pivots 11 lying in the same on saidpipe.

plane at right angles to the trunnions 9 and supported in bearings 12 onthe intake funnel 3. This construction forms the well known gimbalbearing for mounting Ina-rincrs compasses.

To insure a constantly level position for the carluu'eter, a weight 13is hung on a rigid arm 14 extending downwardly from the nozzle, andoperates like a pendulum to correct any tendency of the carbureter totilt. The gusolcne is fed to the float chamher through a flexible tube15.

In accordance with the provisions of the patent statutes. I havedescribed the principle of operation of my invention, together with theapparatus which I now consider to represent the best embodiment thereof;but I desire to have it understood that the apparatus shown is onlyillustrative. and that the invention can be carried out by other means.

What I claim is new and desire to secure by Letters Patent of the UnitedStates, is:

'1. The combination in a carbureter of a stationary intakcpipc. a floatchamber, a nozzle connected therewith, and means for suspending thefloat chamber and nozzle with relation to the intake pipe which permitsthem to automatically maintain a level position when the carbureter istilted.

2. The combination in a carl'iureter of a stationary intake pipe, afloat chamber, a. nozzle connected therewith, and means car.- danicallysuspending the float chamber and nozzle on axes intersecting saidnozzle.

3. A carburetor having its float chamber and nozzle mounted on gimbalsin the plane of the mouth of the nozzle.

4. The combination in a carburetor of a stationary intake pipe, and afloat chamber and nozzle mounted on gimbals supported 5. A carbureterhaving its float chamber and nozzle cardanically suspended on the airintake pipe, and a rigid weighted arm depending below said floatchamber.

In witness whereof I have hereunto set my hand this 20th day of August.1912.
